Abstract
An adjustable voltage reference circuit (14, 25, 70) that can be adjusted via an external device is disclosed. The circuit is designed to receive, after packaging, a plurality of adjustment inputs (20). These inputs are used by an adjustable voltage cell (21, 26, 71) to produce an adjustment factor. The adjustment factor will then be used by a voltage reference cell (22, 27, 72) to adjust the reference voltage (Vref).
